摘要： A base station apparatus, a terminal apparatus, and a communication method that make it possible to achieve reduction in delay of communication are provided. A base station apparatus of the present invention is a base station apparatus for performing communication with a terminal apparatus under a first communication scheme or a second communication scheme. The first and second communication schemes differs in allowable delay time from each other. The base station apparatus notifies the terminal apparatus of pre-scheduling information including information indicating a plurality of resource candidates that are used in the first communication scheme. The base station apparatus enters a receiving operation of the first communication scheme in a resource indicated by the plurality of resource candidates.

摘要： A reduction in interference improves throughput and increase opportunity for communication by each terminal apparatus. A base station apparatus that communicates with a terminal apparatus transmits information relating to a transmit power for a UE-specific reference signal in a state of being included in downlink control information, in a case of a predetermined transmission mode. A terminal apparatus that communicates with a base station apparatus includes a reception unit that receives downlink control information which includes information relating to a transmit power for a UE-specific reference signal, from the base station apparatus, in a case of a predetermined transmission mode, and a reception signal is demodulated based on the downlink control information.

摘要： A coding unit and a radio transmitting unit are included. The coding unit includes a first coding unit, a division unit, and a second coding unit. The first coding unit codes information bits by using first coding. The division unit divides an output from the first coding unit into blocks. The second coding unit performs error correction coding on each of the blocks output by the division unit to generate a coded block. The radio transmitting unit transmits a plurality of the coded blocks at a random transmission timing.

摘要： A signal that is transmitted to a terminal apparatus itself is demodulated with high precision, and throughput is improved. A terminal apparatus that communicates with a base station apparatus includes: a reception unit that receives downlink control information from the base station apparatus; and a signal detection unit that demodulates a signal that is transmitted to the terminal apparatus itself, based on first modulation mapping, and demodulates an interference signal based on second modulation mapping, in a case where information relating to a transmit power of the interference signal is included in the downlink control information. A base station apparatus that communicates with a terminal apparatus includes: a transmission unit that transmits a transmit signal at a different transmit power to each of a plurality of terminal apparatuses, in a case where the plurality of terminal apparatuses are multiplexed with the same resource, and a modulation unit that performs modulation using first modulation mapping for a terminal apparatus that has a minimum transmit power, and performs the modulation using second modulation mapping for other terminal apparatuses.
